David Polster has pioneered the use of soil bioengineering for treatment of riparian areas and unstable slopes in British Columbia.

David's company is Polster Environmental Services Ltd.

As a member of the International Erosion Control Association he has participated in IECA courses investigating bio-technical construction techniques, wet road crossings, and the best management practices for the use of bio-technical applications in landslide and erosion prone terrain.

President P. Raymond

is a senior forest technologist. He has worked for the past thirteen years in the natural resources sector in British Columbia and Alberta. For the last seven years, his focus has been biotechnical slope stabilization for erosion control, and riparian habitat restoration in the East and West Kootenay regions of British Columbia.

In 2002, he was involved in the monitoring, auditing, training and trial establishment for permanent and temporary erosion control measures on a pipeline project in southern Peru. Pierre’s experience includes biotechnical stabilization prescriptions, implementation, maintenance, and monitoring. He also has a strong background in post-harvest silviculture treatment, supervision of construction machinery, and road deactivation practices.

Recent projects include riparian habitat restoration, landslide rehabilitation, roadside stabilization, vegetated riprap, and vegetated log crib walls. Mr. Raymond has owned and operated his company for the past eight years.

Dave Putt

is a geologist who has worked in the forest resources sector of southeastern British Columbia for 11 years with a major focus on terrain hazard assessment and mapping. Applications include control of erosion and slope stability in forest resource development and watershed restoration for protection of fisheries values and community water supplies.

Recent projects in Canada include landslide rehabilitation using biotechnical stabilization techniques and road deactivation as well as erosion control and degraded site rehabilitation in watersheds used for community water supply. In the past 2 years he has worked on a major gas pipeline project in Peru completing assessment of landslide and soil erosion hazards in jungle and high sierra environments as well as auditing control measures. David's company is Forterra Consultants Ltd.

Carol Wallace

P. Geo has been an independent consultant for nine years specializing in geoscience in the forest resource sector. She has been conducting terrain mapping with interpretations of terrain stability and erosion hazards, landslide investigation, and road deactivation. Her work has focused on landslide investigation, as she was the project organizer for the Landslide Attributes Study of the Nelson Region from 1996 to 2001.

Recent projects include fireguard trail rehabilitation and erosion control in watersheds used for community water supply. Her prescriptions incorporated some bioengineering structures in areas with high sediment delivery potential. Recent research projects that she completed are terrain mapping, bedrock mapping, and a sediment source survey in the research sub-watersheds in Cranbrook’s watershed. She also conducted a study for the Faculty of Forestry-Forest Science Centre-Vancouver, BC on landslide run-out zones.
